Yeah, I looked at the walkthrough and tried to solve the puzzle from that but I cannot do it since I cannot see the circle and prisoners. I guess I will have to give up on this game for now. Maybe I will try in Win 7 if I decide I feel like messing up my whole desktop.

I found a video walkthrough and watched this puzzle being solved. I counted the clicks to where the check marks were made and was able to solve the puzzle, so I will be continuing on in the game (at least until/unless I run into another problem that I maybe won't be able to get past).
